E9300/1/4/A Power Sensor Specifications

Switching Point

The Agilent E-series E9300 power sensors have two paths, a low power path covering -60 dBm to -10 dBm, and a high power path covering -10 dBm to

+20 dBm. The power meter automatically selects the proper power level path. To avoid unnecessary switching when the power level is near the -10 dBm point, Switching Point Hysteresis has been added. This hysteresis causes the low power path to remain selected until approximately -9.5 dBm as the power level is increased, above this power the high power path is selected.The high power path remains selected until approximately -10.5 dBm as the signal level decreases, below this power the low power path is selected.

1.RH is the abbreviation for Relative Humidity.

2.Within 1 hour after zero set, at a constant temperature, after a 24 hour warm-up of the power meter with sensor connected.

3.The number of averages at 16 for Normal mode and 32 for x2 mode, at a constant temperature, measured over a one minute interval and two standard deviations.
